What is opencode?

opencode's feed goes quiet after V2 took over, with only CI and animation tags.

The two new tags are housekeeping: the GitHub Action now pins actions/cache to a commit SHA, and an app tag changes how an orb animation is derived. The substantive changes remain V2's promotion to the main branch, the VS Code extension 1.0 that launches the V2 CLI, and the retirement of the separate beta repo.

What is Synthesia?

Synthesia is becoming a general AI video editor — avatars are now one feature, not the product.

Synthesia has spent the last six months extending its product surface well beyond AI avatar generation. The Editor now ingests external screen recordings (MP4 → transcribed, scene-split, editable Synthesia video), accepts .pptx with speaker notes as voiceover, and runs an AI Playground that exposes third-party models — Sora 2, Veo 3.1, FLUX.2, Nanobanana Pro — directly inside the canvas. Avatar capability also broadened: action-taking stock avatars with arbitrary backgrounds, speech regeneration, and per-voice speed control. The release cadence has slowed visibly since March, with no public updates in the past two months.

opencode's feed goes quiet after V2 took over, with only CI and animation tags.

◆ Current state

The two new tags are housekeeping: the GitHub Action now pins actions/cache to a commit SHA, and an app tag changes how an orb animation is derived. The substantive changes remain V2's promotion to the main branch, the VS Code extension 1.0 that launches the V2 CLI, and the retirement of the separate beta repo.

◆ Where it's heading

opencode has spent October consolidating on V2 and cleaning up its release pipeline. The tags since then are small and auxiliary, which suggests the next user-facing release will be a V2 CLI version rather than more 1.18.x patches.

◆ Prediction

Expect the first V2-numbered CLI release to appear next; the entries don't show when.

Synthesia is becoming a general AI video editor — avatars are now one feature, not the product.

◆ Current state

Synthesia has spent the last six months extending its product surface well beyond AI avatar generation. The Editor now ingests external screen recordings (MP4 → transcribed, scene-split, editable Synthesia video), accepts .pptx with speaker notes as voiceover, and runs an AI Playground that exposes third-party models — Sora 2, Veo 3.1, FLUX.2, Nanobanana Pro — directly inside the canvas. Avatar capability also broadened: action-taking stock avatars with arbitrary backgrounds, speech regeneration, and per-voice speed control. The release cadence has slowed visibly since March, with no public updates in the past two months.

◆ Where it's heading

The strategic move is from 'create a video by typing a script for an avatar' to 'turn any input (slides, recordings, prompts) into a Synthesia-editable video,' with third-party genAI models embedded in the canvas. Avatars are repositioning as one input among many, not the headline. The pause in release cadence since March is notable for a product that was shipping every two to three weeks through Q4 2025 — could indicate a larger release in flight, a strategic reorientation, or commercial pressure squeezing the public-facing tempo.

◆ Prediction

The next visible release will likely be the next-generation avatar tier (the action-taking stock avatars were called 'one of the most exciting updates of the year' in November, so an upgrade or open-prompt avatar variant is overdue), or a foundational change to the ingestion pipeline that ties the screen-recording and PowerPoint surfaces into a single 'video from anything' flow. If the silence continues past Q2, that's a signal worth watching.
